Abstract
A disposable biomedical electrode is disclosed wherein the electrically-conductive material between the electrode plate and the skin comprises a swellable, conformable, cohesive, hydrophilic, electrically-conductive adhesive formed by an improved solventless process. The adhesive precursor comprises a polyhydric alcohol, a non-ionic unsaturated free radically polymerizable material, a free radical initiator, a crosslinking agent and an ionizable salt. The adhesive precursor is polymerized after coating onto the electrode plate or releasable transfer sheet, preferably by exposure to ultraviolet radiation.
